Application filed March 16, 1915.

To all whom it may amoem:

Be it known that I, ALBERT BREDIN CRAW- FORD, a subject of the King of Great Britain, residing at 71 Carlisle road, Eastbourne, England, have invented new and useful Improvements in Dress-Fastenings, of which the following is a specification.

This invention relates to wearing apparel fastenings of the press button type.

My invention is illustrated by the accompanying drawing.

Figure 1 is a plan of one member, Fig. 2 is a plan of the other member, Figs. 3 and 4 are sections at right angles to one another of the second member, and Fig. 5 is a section showing the two members engaged.

The first member consists of a plate A from which stand up vertical walls a in the form of a rhomboidal prism, at the top of which is a plate 64 having in it an elliptical opening a the major axis of the ellipse being co-incident or substantially so with the shorter diagonal of the rhombus. The second member consists of a base plate B, a shank c which is cylindrical in form and a head Z) of elliptical shape corresponding to that of the opening a. The two members are secured, say by sewing, to the two portions of fabric which are to be fastened together, and with the orientation shown by Figs. 1 and 2. When the fastening is to be done up, one member must be turned relatively to the other so that the major aXis of the elliptical head I) may be parallel to that of the opening a and the head can then be Specification of Letters Patent.

pressed through the opening; the pull of the fabric, which is in the line of the arrow, will turn the head into the position shown in dots in Fig. 1 and the fastening cannot therefore come undone, until one member is turned relatively to the other so as to bring the major axes of the two ellipses parallel. The vertical walls a only allow of the head Z) turning in one direction (clockwise as seen in Fig. 1) after it has been inserted through the opening a and, when it is turned in the reverse direction, to enable the fastening to be undone, the walls prevent the head from being turned too far, i. 6. beyond the position in which it can be disengaged. The edge of the opening a. may conveniently be beveled as seen in Fig. 5 to facilitate the entry of the part Z). The diameter of the shank 0 is just a shade smaller than the minor axis of the ellipse a.

hat I claim is:

A dress fastening comprising two members, the one formed of a base, vertical walls forming a rhomboidal prism and a plate on the top of the walls having in it an elliptical opening the major axis of the ellipse being coincident with the shorter diagonal of the rhombus, and the second member formed of a base plate, a shank and an elliptical head.
